NOTE:

In dual-controller configurations, firmware on the two controllers is compared each time the

MSA chassis is restarted. If the versions are mismatched, the system prompts to clone the firmware

on the controller with the latest version over to the controller with the earlier version firmware. The

following message is displayed on the LCD panel of the controller with the earlier firmware:

07 CLONE FIRMWARE ? ‘<‘ = NO, ‘>’ = YES

Press the > button on the LCD panel to clone the firmware. During the cloning process, informational

messages are displayed on the controller LCD panels. When the cloning process is complete, the

just-updated controller automatically restarts.

10.

Before resuming I/O access to the MSA, verify that the MSA and its storage arrays are online.

Disabling a controller for removal

In a dual-controller system, this command disables one of the controllers to prepare it for removal. When a

controller is disabled, all resources being processed by that controller are automatically failed over to the

remaining controller. After a controller has been successfully disabled, the LCD panel displays a message

stating that it is safe for that controller to be removed.

NOTE:

This command is available only in dual-controller configurations.

Basic command

disable other_controller

-or-

disable this_controller

-or-

disable standby

Overriding the ACU lock

To prevent simultaneous use of more than one management interface, the system automatically places a

lock on the MSA CLI whenever the Array Configuration Utility (ACU) or the Array Configuration Utility -

Command Line Interface (ACU-CLI) is managing the MSA.
This command can disable the lock and allow the CLI to be used at the same time that the ACU or ACU-CLI

is active.

CAUTION:

Turn off the ACU lock only under strict supervision. Multiple configuration sessions may lead to

contradictory commands, unintended configuration changes, inappropriate actions, or a disrupted status.

Basic command

override aculock

Enabling or disabling debug console logging

To allow additional system level messages to appear on the CLI console during failure events (such as hard

drive, power supply, or fan module failures):

Basic command

set debug
